Finance OS runs the accounting, the payroll, the SARS returns, the financial statements and the Companies Act tests for every client you carry — on an immutable ledger that reconciles continuously, and reports nothing it cannot trace to a posting.
Because Finance OS understands what it holds, it can verify it — continuously, and against the ledger itself. Where the arithmetic does not hold, it stops and reports the difference to the cent, rather than accepting the entry and leaving the problem for year end.
8000 Debtors Control
equals the sum of open invoices, 9000 Creditors Control equals the sum of open bills. If any
check fails, nothing is posted and the difference is reported. The system does not round a book into
balance.Not a bookkeeping app with a tax module bolted on. One ledger, one chart, one source of truth — and every statutory obligation derived from it.
Immutable and append-only. Nothing is edited, nothing is deleted, everything is a posting. A control account can only be written by the subledger that owns it — so debtors control always equals the debtors, by construction rather than by hope.
Invoicing, credit notes, allocations, supplier bills, petty cash on the imprest system, bank import and reconciliation. Photograph a supplier invoice or forward it by email — AEGIS reads it, checks that the lines plus VAT equal the total, and stages it for approval.
Full South African payroll — PAYE, UIF, SDL, ETI — with EMP201, EMP501 and IRP5/IT3(a) built from the actual runs. VAT201 from the actual ledger. Provisional tax and ITR14 from the actual numbers. Nothing re-keyed, so nothing to re-key wrong.
A full IFRS-for-SMEs annual financial statement set, and the assurance documents that go with it — engagement letters, compilation reports under ISRS 4410, working papers. Built from the standards themselves, and from the ledger underneath them.
The section 4 solvency and liquidity test, computed — both limbs, twelve months forward. The Public Interest Score, computed, and with it the reporting framework and assurance level the client actually requires. A company that cannot lawfully declare a dividend is told so before it declares one.
Ask AEGIS a question in plain language and it answers from the ledger. Tell it to do something and it does it — but anything that touches money shows you the exact double entry first, and waits. Thirty financial-health ratios, cash-flow forecasting, anomaly detection. Every number it quotes is computed, never estimated.
Most accounting software is written by reading other accounting software. Finance OS was written by reading the Acts, the standards and the SARS specifications themselves — and the rules are implemented as rules, not as approximations that happen to give the right answer most of the time.
Section 4 — the solvency and liquidity test, both limbs, twelve months forward. Regulation 26(2) — the Public Interest Score, and with it the reporting framework and assurance level a client actually requires. A company that cannot lawfully declare a dividend is told so before it declares one.
Section 21 — a credit note's VAT falls in the credit note's own period and is never backdated; a recipient reverses input tax in that period; a settlement discount on an invoice is not a credit note. The rate is a date-effective parameter, so a prior period keeps the rate that governed it.
A full annual financial statement set to the standard, and the compilation report that accompanies it. Produced from a frozen snapshot, so the figures you signed are the figures you can always reproduce — years later, to a reviewer, without argument.
PAYE, UIF, SDL and ETI computed from the Fourth Schedule, not from a lookup table someone updated once. Payslips to BCEA section 33. EMP201, EMP501 and IRP5/IT3(a) built to the SARS Business Requirements Specification, from the actual payroll runs.
A firm with a hundred and sixty clients cannot open them one at a time. AEGIS shows the principal every client at once — and, more importantly, everything that hasn't happened.
Xero connects directly. Pastel, Sage, QuickBooks and everything else print three reports — a trial balance, a debtors age analysis, a creditors age analysis. That is all AEGIS needs.
It is the right question, and you are entitled to a straight answer rather than a reassuring one. A practice cannot put a hundred and sixty client books inside a young company on faith. So we have answered it in the design of the system, not in a conversation.
One-click trial-balance export — per client, or your whole book as a single file — formatted for CaseWare, today. It is the export your practice would use every day anyway. It is also, if it ever comes to that, the door out. Your working papers and your AFS process never lived inside us to begin with.
Full export of every client — ledger, subledgers, contacts, documents — in open formats, on demand. That is written into the migration agreement before a single client of yours moves across, because a commitment you can enforce is worth more than one we merely make.
Every figure is derived from postings you can see, in a ledger that is append-only. There is no proprietary calculation holding your numbers hostage. A book that came out of AEGIS can be reconstructed and defended without AEGIS.
No client moves until a parallel run has proved the trial balance, the VAT201 and the payroll to R0.00 against your existing system. You are never asked to believe us. You are shown the difference, and it is zero, or the client does not move.
We will not ask you to switch anything. Give us ten client books — the messiest ones, the ones that scare you — and for one month we will run them in parallel while Pastel, Sage or Xero stays your system of record. Nothing changes for you or your clients. At month end we show you, per client: the trial balance difference, the VAT201 difference box by box, and the payroll net-pay difference. The pass mark is R0.00. Not "close". A client that does not tie does not migrate.
